For example, a common
idiom in R is to fit a model like this:
results <- lm(y ~ x)
This command places the results into an object called
"results" (technically of class "lm"), which one can then use later
on. In Stata, this would look like:
reg y x
est store results
which would store the estimation results under the name "results" for
further use. Of course in R you can save the object "results" in a
file, whereas in Stata (at least as of version 9) you cannot save the
set of results in a file (though see Michael Blasnik's -estsave- and
Ben Jann's -estwrite- and -estread- wrappers for a workaround).
